Finite element analysis stress plot of a representation of the modified flexure geometry. The parameters are \(R_{\text{m}}={200}\) mm, \(L_{\text{m}}={20}\) mm, \(R_{\text{a}}={1.5}\) mm, \(L_{\text{a}}={3}\) mm, \(H={5}\) mm, \(w={10}\) mm, and \(h_{0}={0.05}\) mm. Boundary conditions are the same as in Fig. 6. The color bars show the results for the maximum equivalent stress in the flexure after deflection in MPa. The simulation shows a maximum equivalent stress of 359 MPa in the flexure, which is about 36% of the yield strength (≈1000 MPa) of the flexure material
